UV mapping PS to Blender
You shouldn't combine image and noise texture that way.
If you need a non-smooth surface, just use it as a Bump map.


Connect image texture into Base Color input
Use Noise texture with the Bump node and connect it into Height
Connect the Bump node into Normal input




Other observations:


avoid n-gons, they cause bad shading and prevent loopcuts, proper beveling, etc.
use linked duplicates - similar buttons can share the same mesh yet be independently moved/rotated
the main area has 3.74° tilt. Make sure your buttons are tilted consistently.
don't plug Noise texture node into the Specular input, if you're going for realism.
Avoid extreme values in the Noise texture. Use White Noise for fine grain.


Use quads (and tris) when possible.
